Abstract: The signals controlling marginal zone (MZ) and follicular (FO) B cell development remain incompletely understood. Here, we show that AKT orchestrates MZ B cell formation in mice and humans. Genetic models that increase AKT signaling in B cells or abolish its impact on FoxO transcription factors highlight the AKT-FoxO axis as an on-off switch for MZ B cell formation in mice. In humans, splenic immunoglobulin (Ig) D+CD27+ B cells, proposed as an MZ B cell equivalent, display higher AKT signaling than naive IgD+CD27− and memory IgD−CD27+ B cells and develop in an AKT-dependent manner from their precursors in vitro, underlining the conservation of this developmental pathway. Consistently, CD148 is identified as a receptor indicative of the level of AKT signaling in B cells, expressed at a higher level in MZ B cells than FO B cells in mice as well as humans

Altern

Das für ein breites Publikum geschriebene Werk zeigt die kausalen Verbindungen zwischen den messbaren Alterserscheinungen und den zugrundeliegenden Veränderungen in Genen, Zellen und in deren Kommunikationssystemen auf. Molekularbiologische Ansätze gewinnen in Medizin und Pharmakologie immer mehr an Bedeutung (Molekulare Medizin, targeted therapies, genombasierte personalisierte Medizin), und Kenntnisse über kausale Mechanismen der Alterung werden die Vorsorge und Therapie zahlreicher Alterskrankheiten deutlich verbessern können. Die Autoren erläutern diese Zusammenhänge an elf menschlichen Funktionssystemen: Haut, Knochenskelett, Muskulatur, Kreislauf und Lunge, Immunsystem, Verdauun...
